Timepiece with tourbillon mechanism having a support

摘要

A timepiece includes: a frame; a mobile body of a finishing gear train; and a tourbillon mechanism including a holder supporting a balance and at least one escapement. The tourbillon mechanism includes: an outer ring rotatably mounted onto the frame about a first axis; at least one inner ring inside the outer ring and rotatable relative to the outer ring about a second axis, the holder being pivotably mounted in the inner ring and secured to a shaft around which the inner ring is freely and rotatably mounted about a third axis; a first toothed member mounted onto the frame; a first pinion secured to the shaft of the holder to engage with the first toothed member to rotate the holder; and a unit driving the inner ring, engaging with the movable body of the finishing gear train and arranged to move the inner ring and, consequently, the outer ring.

1. A timepiece, comprising:
a frame; at least one wheel of a moving train; and at least one tourbillon mechanism comprising
a support bearing a balance,at least one element of an escapement,
an outer ring rotatably mounted on the frame around a first axis,at least one inner ring mounted inside the outer ring and rotatable relative to the outer ring around a second axis, the support being pivotably mounted in the inner ring and being secured to an arbor around which the inner ring is mounted, freely rotating along a third axis,a first toothed organ, mounted on the frame,a first pinion secured to the arbor of the support arranged to cooperate with said first toothed organ so as to rotate said support, andmeans for driving the inner ring cooperating with a wheel of the moving train and arranged to move the inner ring and the outer ring thereby providing the support a composite movement.
